CAP FOR HOSE CONNECTIONS.

pecification of Letters Patent. Patgnted J 31 1 Application filed September 23, 1920. Serial No. 412,183.

To all whom it may concern:

Be it known that I, ARTHUR C. \ROWLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented Caps for Hose Connections, of which the following is a specification. f

This invention relates to removable closures for so-called steamer or hose pipes, such as are provided at the bases of office, factory and other buildings equipped with fire extinguishing systems, and one of its objects is to provide a relatively simple device for removably retaining a cap in place on such a pipeor connection so as to prevent the accidental or malicious placing therein of solid bodies such as might obstruct the flow of water. j

Another object of the invention is to provide a device for normally holding a cap: on a hose connection so as to prevent its too easy removal, which while being relatively simple and substantial in construction, shall be of such design as to facilitate its quick removal by a person having the necessary knowledge and apparatus.

The invention further contemplates a novel form of retaining strap and frangible lug for normally holding a cap in position over the otherwise open end of a pipe such as a hose connection.

These objects and other advantageous ends I'attain as hereinafter set forth, reference being had to the accompanying drawings, in which,

Fig. 1 is a side elevation, partly in verti cal section, illustrating the end of the coupling member of a hose connection having my invention applied thereto; and

Fig. 2 is a plan of the construction shown in Fig. 1.

In the above drawings, 1-represents a substantially cylindrical casting in the form of a coupling sleeve such as is customarily mounted on the end of a steamer or hoseconnection. This sleeve is provided with two oppositely placed projecting cylindrical lugs 2 and is internally threaded at 3 for the reception of the correspondingly threaded end of a length of hose. For closfrom its edge at opposite points thereof so as to extend downwardly along the side of the said sleeve. These T-shaped lugs are o ned to the body of the cap 4 by relatively thin neck portions 7, preferably notched as indicated at '8 to facilitate their easybreakage and each having projecting upwardly from the center of its top edge or face an extension 8, which, since the top of said lug is substantially flush with the top surface of the cap 4, may easily be struck by ahammer or other tool when it is desired to break the lug free from the cap. The latter is of course made of a material usually cast iron,

which is capable of such breakage.

The two oppositely projecting arms of each of the T-shaped lugs 6 extend substantially parallel with and are spaced away from straight portions of the adjacent edge of the cap 4, defining slots adjacent which the top face of said cap is formed with relatively shallow, substantially rectangular recesses or depressions 9. These latter are designed to receive the bent over ends 10 of a metallic strap 11, whose central portion is curved around one of the projecting lugs 2 of the sleeve 1 and whoseside members extend between the latter and the cross arms of the lugs 6 through the slots 12, above which they are turned at right angles so as to lie within said recesses 9.

The straps 11 are made of more or less springy, non-corrodible metal and afterthe cap 1 has been centered by its rib 5 on the through the slots 8, thus freeing the straps 11 and permitting said cap to drop ofit'.- A water supply hose may'thereupon be made,

with the certainty that there will be'no obstruction in the line of pipe'connected to the sleeve 1, such as might interfere with the flow of water.

Tclaim: 1. A cap for a hose connection consisting of a plate having projecting lugs connected to it through relatively frangible necksyeach of said lugs having an. upward extension to facilitate its breakage from the plate.

2. A closure for a hose connectioncoin sistin of a plate havin lugs )ro'ectin b a b U C from its ec gos and each including oppositely extending portions spaced away from the plate to provide slots.

' 3; A clcsurefor a hose connection consist ing of a plate having lugs projecting from its edges and each including oppositely extending portions spaced awa from the plate to provide two slots, there being recesses formed in the plate adjacent said slots respectively.

4:. Es; closure for a hose connection consisting of a plate having substantially T-shapedlugs connected to it by frangible necks, the top arms of each of the lugs being spaced away from the edge of the plate.

5. Aclosure for a hose connection consistr ing of a plate having substantially T-shaped connected to it by frangible necks and each separated from said plate by two relatively narrow slots; with straps each having its body extended around one of the lugs of the hose connection and its ends extended through the slots onto the top face of the plate. 7

' 7 The combination o1 a tubular structure having projecting lugs; a plate closing the end of said structure and having two substantially T-shaped lugs connected to it by frangible necks; with straps having their ends at right angles to their side'portions and projected over the plate, the side portions of each of said straps extending respectively between the plate and the arms of one of the lugs thereof and passing around the lugs of the tubular structure.

8. The combination of a tubular structure having projecting lugs; a plate closing the end of said. structure and having two substantially T-shaped lugs connected to it by frangible necks; with straps each having its ads at right angles to its side portions and projected over the plate, the side portions of each strap extending respectively between the plate and lugs and passing around the lugs of the structure; with upward exten sions from each of the plate lugs.
